Brother John of Alvernia, while yet a boy and living in the world, desired with all his heart to tread the path of penitence that keepeth pure both body and soul, whereby being still a little child, he began to wear the shirt of mail and iron girdle on his flesh, and to use great abstinence and above all, he shunned all carnal delights and mortified his body with great severity of abstinence but inspired of God he minded to leave the world with the lovers thereof, and to offer himself wholly unto the arms of the Crucified, in the habit of the crucified Saint Francis; and even so he did.
And being received into the Order while yet a boy, and committed unto the care of the master of the novices, he became so spiritually minded and so devout, that many a time hearing the said master speaking of God, his heart would melt like wax before the fire; and the love of God kindled in him such sweetness of grace, that not being able to remain still to endure such sweetness, he would get up, and as one drunken in spirit, would run, now through the garden, now through the wood, now through the church, according as the flame and the ardour of the spirit drave him.
The divine grace made this angelic soul to grow continually from virtue unto virtue, and in heavenly gifts, being uplifted unto God and rapt in ecstasy; so that at one time his mind was lifted up to the splendours of the Cherubim, at another time to the ardours of the Seraphim, at another to the joys of the Blessed, at another to the loving and ineffable embraces of Christ. And above all, once upon a time in exceeding wondrous fashion his heart was kindled with the fire of love divine, and this flame lasted in him for full three years, in which time he received marvellous consolations and visitations divine, and oftentimes was rapt in God, and in short, in the said time he seemed all on fire and burning with the love of Christ; and all this was on the holy mount of Alvernia.
Who today would counsel a young boy to wear penitential clothes? At least the Franciscans of the time let him run, run, run, like Zorba and his dancing. But things take a turn after three years.
